Each such Holder shall then have three Business Days (or one Business Day in the case of a bought or overnight Underwritten Offering) after the date on which the Holders received notice pursuant to this Section 2.02(b) (the “Notice Response Period”) to request inclusion of Registrable Securities in the Shelf Underwritten Offering (which request shall specify the maximum number of Registrable Securities intended to be disposed of by such Holder and such other information as is reasonably required to effect the inclusion of such Registrable Securities) (any such Holder making such request, a “Shelf Piggybacking Holder”).

(c)    If the Managing Underwriter of the Shelf Underwritten Offering shall inform the Company and the Requesting Holders in writing, with a copy to be provided upon request to any Shelf Piggybacking Holder, of its good faith belief that the number of Registrable Securities requested to be included in such Shelf Underwritten Offering by the Shelf Piggybacking Holders (and any other shares of Company Common Stock requested to be included by any other Persons having registration rights with respect to such offering), when added to the number of Registrable Securities proposed to be offered by the Requesting Holders, would materially adversely affect such offering, then the Company shall include in the applicable Underwritten Offering Filing, to the extent of the total number of Registrable Securities that the Company is so advised can be sold in such Shelf Underwritten Offering without so materially adversely affecting such offering (the “Section 2.02 Maximum Number of Shares”), Registrable Securities in the following priority:

(i)    First, all Registrable Securities that the Requesting Holder and Shelf Piggybacking Holders requested to be included therein (the “Requesting Holder and Shelf Piggybacking Holders Securities”) (pro rata among the Requesting Holders and Shelf Piggybacking Holders based on the number of Registrable Securities each requested to be included); and

(ii)    Second, to the extent that the number of Requesting Holder and Shelf Piggybacking Holders Securities is less than the Section 2.02 Maximum Number of Shares, the shares of Company Common Stock requested to be included by any other Persons having registration rights with respect to such offering, pro rata among such other Persons based on the number of shares of Company Common Stock each requested to be included.

(d)    The Company shall be entitled, subject to the Requesting Holder’s consent (which is not to be unreasonably withheld, conditioned or delayed), to select the Managing Underwriter in connection with any Shelf Underwritten Offering. The Requesting Holders shall determine the pricing of the Registrable Securities offered pursuant to any Shelf Underwritten Offering and the applicable underwriting discounts and commissions and determine the timing of any such Shelf Underwritten Offering, subject to Section 2.03.

Section 2.03    Delay and Suspension Rights. Notwithstanding any other provision of this Agreement, the Company may (a) delay filing or effectiveness of a Shelf Registration Statement (or any amendment thereto) or effecting a Shelf Underwritten Offering or (b) suspend the Holders’ use of any prospectus that is a part of a Shelf Registration Statement upon written notice to each Holder whose Registrable Securities are included in such Shelf Registration Statement (provided that in no event shall such notice contain any material non-public information regarding the Company) (in which event such Holder shall discontinue sales of Registrable Securities pursuant to such Registration Statement but may settle any then-contracted sales of Registrable Securities), in each case for a period of up to (i) 60 days if such period begins on or before the date that is six months after the date hereof or (ii) 90 days if such period begins after the date that is six months after the date hereof, in each case if the Board determines, in good faith, that (w) such delay or suspension is in the best interest of the Company and its stockholders generally due to a pending financing or other transaction involving the Company, including a proposed sale of shares of Company Common Stock by the Company for its own account, (x) such registration or offering would render the Company unable to comply with applicable securities laws, (y) such registration or offering would require disclosure of material

information that the Company would otherwise not have to disclose at such time or (z) such registration or offering would be materially detrimental to the Company (any such period, a “Suspension Period”); provided, however, that the Company may not exercise its delay and suspension rights under this Section 2.03 more than (i) once prior to the date that is six months after the date hereof or (ii) twice in any twelve consecutive month period. For the purposes of calculating the number of days of one or more Suspension Periods under this Section 2.03, such number shall include any number of days during the applicable period during which the Holders were obligated to discontinue their disposition of Registrable Securities pursuant to Section 2.06(b) of this Agreement.

Section 2.04    Piggyback Registration Rights.

(a)    Subject to Sections 2.04(c) and 2.12, if the Company at any time proposes to file an Underwritten Offering Filing for an Underwritten Offering of shares of Company Common Stock for its own account (a “Piggyback Underwritten Offering”), it will give written notice of such Piggyback Underwritten Offering to each Holder, which notice shall be held in strict confidence by such Holders and shall include the anticipated filing date of the Underwritten Offering Filing and, if known, the number of shares of Company Common Stock that are proposed to be included in such Piggyback Underwritten Offering, and of such Holders’ rights under this Section 2.04(a). Such notice shall be given promptly (and in any event at least five Business Days before the filing of the Underwritten Offering Filing or two Business Days before the filing of the Underwritten Offering Filing in connection with a bought or overnight Underwritten Offering) (a “Piggyback Notice”); provided, that if the Piggyback Underwritten Offering is a bought or overnight Underwritten Offering and the Managing Underwriter advises the Company in writing that the giving of notice pursuant to this Section 2.04(a) would adversely affect the offering, no such notice shall be required (and such Holders shall have no right to include Registrable Securities in such bought or overnight Underwritten Offering). Each such Holder shall then have three Business Days (or one Business Day in the case of a bought or overnight Underwritten Offering) after the date on which the Holders received notice (the “Piggyback Notice Response Period”) pursuant to this Section 2.04(a) to request inclusion of Registrable Securities in the Piggyback Underwritten Offering (which request shall specify the maximum number of Registrable Securities intended to be disposed of by such Holder and such other information as is reasonably required to effect the inclusion of such Registrable Securities) (any such Holder making such request, a “Piggybacking Holder”). If no request for inclusion from a Holder is received within the Piggyback Notice Response Period, such Holder shall have no further right to participate in such Piggyback Underwritten Offering. Subject to Section 2.04(c), the Company shall use its commercially reasonable efforts to include in the Piggyback Underwritten Offering all Registrable Securities that the Company has been so requested to include by the Piggybacking Holders; provided, however, that if, at any time after giving written notice of a proposed Piggyback Underwritten Offering pursuant to this Section 2.04(a) and prior to the execution of an underwriting agreement with respect thereto, the Company shall determine for any reason not to proceed with or to delay such Piggyback Underwritten Offering, the Company shall give written notice of such determination to the Piggybacking Holders (which such Holders will hold in strict confidence) and (i) in the case of a determination not to proceed, shall be relieved of its obligation to include any Registrable Securities in such Piggyback Underwritten Offering (but not from any obligation of the Company to pay the Registration Expenses in connection therewith), and (ii) in the case of a determination to delay, shall be permitted to delay inclusion of any Registrable Securities for the same period as the delay in including the shares of Company Common Stock to be sold for the Company’s account.

(b)    Each Holder shall have the right to withdraw its request for inclusion of its Registrable Securities in any Piggyback Underwritten Offering at any time prior to the execution of an underwriting agreement with respect thereto by giving an Opt-Out Notice to the Company requesting that such Holder not receive notice from the Company of any proposed Piggyback Underwritten Offering; provided, however, that such Holder may later revoke any such Opt-Out Notice in writing; provided, further, that if the Company has provided a Piggyback Notice at the time a Holder revokes its Opt-Out Notice, such revocation shall not extend the Piggyback Notice Response Period. Following receipt of an Opt-Out Notice from a Holder (unless subsequently revoked), the Company shall not, and shall not be required to, deliver any notice to such Holder pursuant to this Section 2.04 and such Holder shall no longer be entitled to participate in any Piggyback Underwritten Offering.

(c)    If the Managing Underwriter of the Piggyback Underwritten Offering shall inform the Company in writing of its good faith belief that the number of Registrable Securities requested to be included in such Piggyback Underwritten Offering, when added to the number of shares of Company Common Stock proposed to be offered by the Company (and any other shares of Company Common Stock requested to be included by any other Persons having registration rights on parity with the Piggybacking Holders with respect to such offering), would materially adversely affect such offering, then the Company shall include in such Piggyback Underwritten Offering, to the extent of the total number of securities which the Company is so advised can be sold in such offering without so materially adversely affecting such offering (the “Section 2.04 Maximum Number of Shares”), shares of Company Common Stock in the following priority:

(i)    First, if the Piggyback Underwritten Offering is for the account of the Company, all shares of Company Common Stock that the Company proposes to include for its own account (the “Company Securities”); and

(ii)    Second, if the Piggyback Underwritten Offering is for the account of the Company, to the extent that the number of Company Securities is less than the Section 2.04 Maximum Number of Shares, the shares of Company Common Stock requested to be included by the Piggybacking Holders and holders of any other shares of Company Common Stock requested to be included by Persons having rights of registration on parity with the Piggybacking Holders with respect to such offering, pro rata among the Piggybacking Holders and such other holders based on the number of shares of Company Common Stock each requested to be included.

(d)    The Company shall select the underwriters in any Piggyback Underwritten Offering and shall determine the pricing of the shares of Company Common Stock offered pursuant to any Piggyback Underwritten Offering, the applicable underwriting discounts and commissions and the timing of any such Piggyback Underwritten Offering.

(a)    In connection with any Underwritten Offering contemplated by Sections 2.02 or 2.04, the underwriting agreement into which each Selling Holder and the Company shall enter into shall contain such representations, covenants, indemnities (subject to Article III) and other rights and obligations as are customary in Underwritten Offerings of securities by the Company; provided that the Company shall not be required to make any representations or warranties with respect to written information specifically provided by a Selling Holder for inclusion in the applicable Registration Statement. No Selling Holder shall be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Selling Holder’s authority to enter into such underwriting agreement and to sell, and its ownership of and title to, the securities being registered on its behalf, its intended method of distribution and any other representation required by law or reasonably requested by the underwriters.

(b)    Any participation by Holders in a Piggyback Underwritten Offering shall be in accordance with the plan of distribution of the Company.

Section 2.07    Cooperation by Holders. The Company shall have no obligation to include Registrable Securities of a Holder in any Registration Statement or Underwritten Offering if such Holder has failed to timely furnish such information that the Company determines, after consultation with its counsel, is reasonably required in order for any registration statement or prospectus supplement, as applicable, to comply with the Securities Act.

Section 2.08    UW Lock-Up Agreements.

(a)    In connection with any Underwritten Offering contemplated by Section 2.02, if reasonably requested by the Managing Underwriter of such Underwritten Offering, each Holder of Registrable Securities participating in such Underwritten Offering shall enter into a customary lock-up agreement with the Managing Underwriter of such Underwritten Offering to not make any sale or other disposition of any Company Common Stock owned by such Holder (a “UW Lock-Up Agreement”); provided that all executive officers and directors of the Company are bound by and have entered into substantially similar UW Lock-Up Agreements on terms no more favorable than any UW Lock-Up Agreement to be entered into by a Holder in connection with such Underwritten Offering; provided further, that nothing herein, and no UW Lock-Up Agreement, shall prevent any Holder from (i) making a distribution of Registrable Securities to any of its partners, members or

stockholders thereof or a transfer of Registrable Securities to an Affiliate that is otherwise in compliance with the applicable securities laws, so long as such distributees or transferees, as applicable, agree to be bound by the restrictions set forth in this Section 2.08 or (ii) making sales of shares of Company Common Stock that were purchased in the open market; and provided further, that the foregoing provisions shall only be applicable to the Holders if all Holders are treated similarly with respect to any release prior to the termination of the lock-up period such that if any Holder is released, then all Holders shall also be released to the same extent on a pro rata basis. The Company may impose stop-transfer instructions with respect to the shares of Company Common Stock (or other securities) subject to a UW Lock-Up Agreement until the end of the applicable period of such UW Lock-Up Agreement. The provisions of this Section 2.08 shall cease to apply to such Holder once such Holder no longer beneficially owns any Registrable Securities.

Section 2.09    Expenses. The Company shall be responsible for all Registration Expenses incident to its performance of or compliance with its obligations under this Article II. Each Selling Holder shall pay its pro rata share of all Selling Expenses in connection with any sale of its Registrable Securities hereunder.

Section 2.10    Other Registration Rights. From and after the date hereof, the Company shall not, without the prior written consent of the Majority Holders, enter into any agreement with any current or future holder of any securities of the Company that would allow such current or future holder to require the Company to include securities in any registration statement filed by the Company for such Holders on a basis other than pari passu with, or expressly subordinate to, the piggyback rights of the Holders hereunder provided, that in no event shall the Company enter into any agreement that would permit another holder of securities of the Company to participate on a pari passu basis (in terms of priority of cut-back based on advice of underwriters) with a Requesting Holder or a Shelf Piggybacking Holder in a Shelf Underwritten Offering.

Section 2.11    Opt-Out Notices. Any Holder may deliver written notice (an “Opt-Out Notice”) to the Company requesting that such Holder not receive notice from the Company of the proposed filing of any Shelf Underwritten Offering, Piggyback Underwritten Offering, the withdrawal of any Shelf Underwritten Offering or Piggyback Underwritten Offering or any event that would lead to a Suspension Period as contemplated by Section 2.03; provided, however, that such Holder may later revoke any such Opt-Out Notice in writing; provided, further, that if the Company has provided a Holder Demand Notice or a Piggyback Notice at the time a Holder revokes its Opt-Out Notice, such revocation shall not extend the Notice Response Period or the Piggyback Notice Response Period, as applicable. Following receipt of an Opt-Out Notice from a Holder (unless subsequently revoked), the Company shall not deliver any notice to such Holder pursuant to Section 2.02, Section 2.03, Section 2.04 or Section 2.06, as applicable, and such Holder shall no longer be entitled to the rights associated with any such notice and each time prior to a Holder’s intended use of an effective Registration Statement, such Holder will notify the Company in writing at least two Business Days in advance of such intended use, and if a notice of a Suspension Period was previously delivered (or would have been delivered but for the provisions of this Section 2.11) and the Suspension Period remains in effect, the Company will so notify such Holder, within one Business Day of such Holder’s notification to the Company, by delivering to such Holder a copy of such previous notice of such Suspension Period, and thereafter will provide such Holder with the related notice of the conclusion of such Suspension Period immediately upon its availability.

Section 2.12    Holder Lock-Up Agreements. Notwithstanding anything to the contrary in this Agreement, none of the rights of any Holder set forth herein shall be effective, and the Company shall have no obligations to any Holder hereunder, unless and until such time as Holders that collectively own at least 94% of the Shares outstanding as of the Closing have delivered to the Company Lock-Up Agreements, duly and validly executed by each such Holder.

Section 2.13    Non-Affiliate Status. The Company acknowledges and agrees that no Holder is an Affiliate of the Company as of the date of this Agreement.

Section 3.01    Indemnification by the Company. The Company will indemnify and hold harmless each Selling Holder, its officers and directors and each Person (if any) that controls such Holder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages, liabilities, costs and expenses (including attorneys’ fees) (“Losses”) caused by, arising out of, resulting from or related to any untrue statement or alleged untrue statement of a material fact (a) contained in any Registration Statement relating to the Registrable Securities (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (b) included in any prospectus relating to the Registrable Securities (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus, or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, provided, however, that such indemnity shall not apply to that portion of such Losses caused by, or arising out of, any untrue statement, or alleged untrue statement or any such omission or alleged omission, to the extent such statement or omission was made in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of such Holder expressly for use therein.

Section 3.02    Indemnification by the Holders. Each Holder agrees to indemnify and hold harmless the Company, its officers and directors and each Person (if any) that controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all Losses caused by, arising out of, resulting from or related to any untrue statement or alleged untrue statement of a material fact (a) contained in any Registration Statement relating to Registrable Securities (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (b) included in any prospectus relating to the Registrable Securities (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus, or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, only to the extent such statement or omission was made in reliance upon and in conformity with information furnished in writing by or on behalf of such Holder expressly for use in any Registration Statement or prospectus relating to the Registrable Securities, or any amendment or supplement thereto, or any preliminary prospectus.

Section 3.03    Indemnification Procedures. In case any proceeding (including any governmental investigation) shall be instituted involving any Person in respect of which indemnity may be sought pursuant to Section 3.01 or 3.02, such Person (the “Indemnified Party”) shall promptly notify the Person against whom such indemnity may be sought (the “Indemnifying Party”) in writing (provided that the failure of the Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Article III, except to the extent the Indemnifying Party is actually prejudiced by such failure to give notice), and the Indemnifying Party shall be entitled to participate in such proceeding and, unless in the reasonable opinion of outside counsel to the Indemnified Party a conflict of interest between the Indemnified Party and Indemnifying Party may exist in respect of such claim, to assume the defense thereof jointly with any other Indemnifying Party similarly notified, to the extent that it chooses, with counsel reasonably satisfactory to such Indemnified Party, and after notice from the Indemnifying Party to such Indemnified Party that it so chooses, the Indemnifying Party shall not be liable to such Indemnified Party for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that (a) if the Indemnifying Party fails to assume the defense or employ counsel reasonably satisfactory to the Indemnified Party, (b) if such Indemnified Party who is a defendant in any action or proceeding which is also brought against the Indemnifying Party reasonably shall have concluded that there may be one or more legal defenses available to such Indemnified Party which are not available to the Indemnifying Party or (c) if representation of both parties by the same counsel is otherwise inappropriate under applicable standards of professional conduct then, in any such case, the Indemnified Party shall have the right to assume or continue its own defense as set forth above (but with no more than one firm of counsel for all Indemnified Parties in each jurisdiction, except to the extent any Indemnified Party or Indemnified Parties reasonably shall have concluded that there may be legal defenses available to such party or parties which are not available to the other Indemnified Parties or to the extent representation of all Indemnified Parties by the same counsel is otherwise inappropriate under applicable standards of professional conduct) and the Indemnifying Party shall be liable for any expenses therefor. No Indemnifying Party shall, without the written consent of the Indemnified Party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the Indemnified Party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the Indemnified Party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any Indemnified Party.

Section 3.04    Contribution.

(a)    If the indemnification provided for in this Article III is unavailable to an Indemnified Party in respect of any losses, claims, damages or liabilities in respect of which indemnity is to be provided hereunder, then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall to the fullest extent permitted by law contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative fault of such party in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company (on the one hand) and a Holder (on the other hand) shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(b)    The Company and each Holder agree that it would not be just and equitable if contribution pursuant to this Article III were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in Section 3.04(a). The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages or liabilities referred to in Section 3.04(a) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Article III, no Holder shall be liable for indemnification or contribution pursuant to this Article III for any amount in excess of the net proceeds of the offering received by such Holder, less the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

With a view to making available the benefits of certain rules and regulations of the Commission that may permit the resale of the Registrable Securities without registration, the Company agrees to use its commercially reasonable efforts to:

(a)    make and keep public information regarding the Company available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times from and after the date hereof;

(b)    file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act at all times from and after the date hereof; and

(c)    so long as a Holder owns any Registrable Securities, furnish (i) to the extent accurate, forthwith upon request, a written statement of the Company that it has complied with the reporting requirements of Rule 144 under the Securities Act and (ii) unless otherwise available via

the Commission’s EDGAR filing system, to such Holder forthwith upon request a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration.

Section 5.01    Share Legend.

(a)    Each certificate or book-entry notation representing the Shares shall (unless otherwise permitted by the provisions of Section 5.01(b)) bear a legend in substantially the following form:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM.

(b)    The legend on any shares of Company Common Stock covered by this Agreement shall be removed if (i) such shares of Company Common Stock are sold pursuant to an effective registration statement, (ii) a registration statement covering the resale of such shares of Company Common Stock is effective under the Securities Act and the applicable holder of such share of Company Common Stock delivers to the Company a representation letter agreeing that such shares of Company Common Stock will be sold under such effective registration statement, (iii) such shares of Company Common Stock may be sold by the holder thereof free of restrictions pursuant to Rule 144(b) under the Securities Act or (iv) such shares of Company Common Stock are being sold, assigned or otherwise transferred pursuant to Rule 144 under the Securities Act; provided, that with respect to clause (iii) or (iv) above, the holder of such shares of Company Common Stock has provided all necessary documentation and evidence (which may include an opinion of counsel) as may reasonably be required by the Company to confirm that the legend may be removed under applicable securities law. The Company shall cooperate with the applicable holder of Company Common Stock covered by this Agreement to effect removal of the legend on such shares pursuant to this Section 5.01(b) as soon as reasonably practicable after delivery of notice from such holder that the conditions to removal are satisfied (together with any documentation required to be delivered by such holder pursuant to the immediately preceding sentence). The Company shall bear all direct costs and expenses associated with the removal of a legend pursuant to this Section 5.01(b).

Section 5.02    Transfer of Rights. The rights to registration and other rights under this Agreement may be assigned to a Transferee of Registrable Securities if such Transferee is a Permitted Transferee.

Section 6.01    Termination. This Agreement shall terminate, and the parties shall have no further rights or obligations hereunder, on the earliest of: (a) as to any Holder, on such earlier date on which both (i) such Holder, together with such Holder’s Affiliates, owns less than 1.0% of the issued and outstanding shares of Company Common Stock and (ii) all Registrable Securities owned by such Holder and such Holder’s Affiliates have been sold without restriction pursuant to Rule 144 under the Securities Act and the Company is compliant with Rule 144(c) under the Securities Act, (b) the mutual written consent of all parties or (c) the second anniversary of the date hereof.

Section 6.02    Severability. If any provision of this Agreement shall be determined to be illegal and unenforceable by any court of law, the remaining provisions shall be severable and enforceable in accordance with their terms.

Section 6.03    Governing Law; Waiver of Jury Trial.

(a)    This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to principles of conflicts of laws that would direct the application of the laws of another jurisdiction.

(b)    THE PARTIES HEREBY WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY ANY PARTY AGAINST ANOTHER IN ANY MATTER WHATSOEVER ARISING OUT OF OR IN RELATION TO OR IN CONNECTION WITH THIS AGREEMENT. FURTHER, NOTHING HEREIN SHALL DIVEST A COURT OF COMPETENT JURISDICTION OF THE RIGHT AND POWER TO GRANT A TEMPORARY RESTRAINING ORDER, TO GRANT TEMPORARY INJUNCTIVE RELIEF, OR TO COMPEL SPECIFIC PERFORMANCE OF ANY DECISION OF AN ARBITRAL TRIBUNAL MADE PURSUANT TO THIS PROVISION.

Section 6.04    Adjustments Affecting Registrable Securities. The provisions of this Agreement shall apply to any and all shares of capital stock of the Company or any successor or assignee of the Company (whether by merger, consolidation, sale of assets or otherwise) which may be issued in respect of, in exchange for or in substitution for Registrable Securities, by reason of any stock dividend, split, reverse split, combination, recapitalization, reclassification, merger, consolidation or otherwise in such a manner and with such appropriate adjustments as to reflect the intent and meaning of the provisions hereof and so that the rights, privileges, duties and obligations hereunder shall continue with respect to the capital stock of the Company as so changed.

Section 6.05    Binding Effects; Benefits of Agreement. This Agreement shall be binding upon and inure to the benefit of the Company and its successors and assigns and each Holder and its successors and assigns. Except as provided in Section 5.02, neither this Agreement nor any of the rights, benefits or obligations hereunder may be assigned or transferred, by operation of law or otherwise, by any Holder without the prior written consent of the Company.

Section 6.06    Notices. All notices or other communications which are required or permitted hereunder shall be in writing and shall be deemed to have been given if (a) personally delivered, (b) sent by nationally recognized overnight courier, (c) sent by registered or certified mail, postage prepaid, return receipt requested, or (d) sent by email.

Section 6.07    Modification; Waiver. This Agreement may be amended, modified or supplemented only by a written instrument duly executed by the Company, the Unitholder Representative and the Majority Holders; provided, however, that this Agreement may not be amended, modified or supplemented in a manner that is disproportionately adverse to the rights of a Holder under this Agreement as compared to the other Holders under this Agreement without the prior written consent of such Holder. No course of dealing between the Company and the Holders (or any of them) or any delay in exercising any rights hereunder will operate as a waiver of any rights of any

party to this Agreement. The failure of any party to enforce any of the provisions of this Agreement will in no way be construed as a waiver of such provisions and will not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms.

Except as otherwise expressly provided herein, this Agreement constitutes the entire agreement among the parties pertaining to the subject matter hereof and supersedes all prior and contemporaneous agreements and understandings of the parties in connection therewith.

Section 6.09    Counterparts. This Agreement may be executed in any number of counterparts, and each such counterpart shall be deemed to be an original instrument, but all such counterparts taken together shall constitute but one agreement.
